WASHINGTON (CNN) - Former Secretary of State Henry Kissinger used a short speech at the State Department on Wednesday to joke about the prospect of Hillary Clinton running for President in 2016.

Standing on stage with five other former or current secretaries of state, Kissinger - who served as secretary of state under Presidents Richard Nixon and Gerald Ford - highlighted the work of diplomats and foreign service officers as he spoke at the groundbreaking for the United States Diplomacy Center, a museum set to honor diplomatic work.

WASHINGTON (CNN) - Senate Republican Leader Mitch McConnell holds a slim four-point edge over his Democratic challenger Alison Lundergan Grimes in a new CNN/ORC International Poll of one of the most closely watched Senate races of 2014.

McConnell's 4-point advantage, 50%-46%, falls within the survey's 4-point sampling error, furthering emphasizing how close this Kentucky contest remains 62 days before Election Day. The outcome of this election may help decide control of the Senate, influence President Barack Obama's final two years in office and determine the political fate of Kentucky's longest-serving senator.
